BOTTLE-STOPPER.

Specification of Letters Patent.

Application filed. July 23, 1912.

Patented June 2, 1914-.

Serial No. 711,084.

To all tu/1,0m it may concern Be it known that l, lli-unir A. Koenen, acitizen of the United States, residing in Philadelphia, Pennsylvania,have invented certain improvements in Bottle-Stoppers, of which thefollowing is a specification.

@ne object of my invention is to provide a novel and relatively simpleform of bottle stopper having its parts so arranged as to permit of theflow of successive small amounts of liquid from the bottle and toprevent flow of liquid in the opposite direction.

lt is further desired to provide a bottle stopper of the above notedtype which shall be particularly adapted for use in connection withbottles designed to contain preparations for application to the scalp',the conn struction being such that the various parts shall be convenientand inexpensive to man ufacture as well as certain in action.

These objects and other advantageous ends, l secure as hereinafter setforth, reference being had to the accompanying drawings, in which-Figure 1 is an enlarged vertical section of the upper portion of abottle illustrating my invention as applied thereto; Figs. 2, 3 and 4are side elevations of the valve seat structure, and spring formingparts of my invention; Fig. 5 is a side elevation of the stopper shownin Fig. 1; Fig. 6 is a vertical section of the cage structure; Fig. 7 isa horizontal section on the line c--c, Fig. 1, and Fig. 8 is a verticalsection of a modified form of my invention.

ln the above drawings, 1 represents a bottle whose mouth in the presentinstance is provided with an outwardly extended flange 2. Over saidmouth of the bottle and inclosing the same together with certain partshereafter described, l mount a substantially conical casing 3,terminating at its apex in a tubular extension 4L provided with a rela.-tively restricted outlet passage 5 and designed for the reception of acap G.

Resting upon the top of the bott-le is a valve seat structure having asubstantially semi-cylindrical portion 7, extending downwardly into thebottle neck and formed with a flange 7L turned over the flange Sa of avalve guiding structure or cage 8, so that the two structures make aliquid proof joint and are held in place by the casing 3. The downwardlyextending part 7 is provided with a substantially conical hole and formsa seat for a hollow conical valve 9 whose upper end extends into thecage structure d and is capable of foming a liquid tight joint with anannular seat l() therein.

The main portion of the cage structure S as shown is substantiallycylindrical with its upper end seinrspherical in form and provided witha central outlet 11 which like the passage 5 in the casing 3, is of arelatively small area of cross section. In the inner surface of thewalls of the cage S, l form. a number of elongated grooves 12 extendingfro-m points beyond the seat 10 to the lower end or face of said cage;it being noted that the body of the valve 9 is substantially cylindricaland has a sliding lit within the said cage; being normally held to itsseat by a light spring 13. l preferably form the various parte il, 7, Sand 9 of aluminum and in attaching the casing 3 to the neck of thebottle, l place a gasket 111 of suitable material under the bottle lipor flange and turn the lower edge of said casing over this gasket asshown, in Fig. 1.

As the stopper forming my invention is particularly designed for use onbottles containing relatively thin liquid such as water or alcoholicsolutions, a reciprocating jerky movement of the bottle when in theinverted position will cause the valve 9 to move away from the seatstructure 7 against the action of the spring 13 so that the liquid isfree to pass through the valve seat into the hollow interior of saidstructure 7, thence through the side grooves 12 of the cage 8 and out ofthe restricted opening 11 in said easing 3, from whence it flows fromthe outlet 5 after the cap G is removed. Obviously such flow will resultin the delivery of measured quantities of liquid, for the valve coactingwith the cage 8 has a greater or less piston action.

lt is to be noted that my improved stopper is of such construction as tomake it eX- tremely ditlicult if not impossible to relill the bottle towhich it is aplilied after the latter has once been emptied ,-thisdesirable end being due to the peculiar form and arrangement of valve,seat, and cage structures in combination with the spring and therestricted outlet openings.

ln some cases the casing 3 and cage structure 8 may be formed as asingle integral piece 3 of glass or porcelain as shown in. Fig. 8, inwhich case the valve seat struc ture would be held between the top ofthe bottle and said piece while the latter; would be cemented orotherwise permanently fixed to said bottle. In the Structure illustratedthe part 3a has its external surface flush with the outside surface ofthe bottle neck.

l claim:

The combination with a bottle of a suh- Stantially semi-Spherical hollowStructure extending downwardly into the neck thereof anid having' aflange resting on the top of Said neck, there being a substantiallyconical opening` through the center of Said Structure; an upwardlyextending` relatively elongated cage structure having a flange restingon the flange of the seat structur and provided with a substantiallycylindrical interior cavity havinglongitudinally two Subscribingwitnesses.
